I have never seen 80 Mbs over LTE anyplace, much less in NY NJ - are you sure you are referring to the right metric here? Take a look at the Mossberg article recently comparing ATT and Verizon LTE speeds on Recode. Best average for major metro area with good coverage is 20 mb. I typically get 5-10 in central NJ and have never seen better than 10 to 20 or so. I seldom even get close to 50mb over Fios WiFi. In NYC is hit or miss depending on congestion and coverage and I've seen as good as 25 MB infrequently and an occasional crawl at 1 MB in the middle of Times Square. More often than not its a struggle to even get a single walking down the street at all as my phone gulps battery trying to find a signal... although it has gotten better.
The article is from March 2015 - not sure if they have made significant improvements since then - and I'd love to get 80 mb, but that seems crazy high. If I recall, FIOS would charge me extra for 75MB to my house than 50 MB and that is over fiber.
